attribute	NC_GLOBAL	acquisition_description	String	The sediment trap array was deployed at the beginning and recovered at the end of each experimental cycle.The array consisted of two VERTEX-style particle interceptor tube (PIT) crosspieces (Knauer et al. 1979, Stukel et al. 2013), deployed at what investigators initially thought to be the base of the euphotic zone (100 m on cycle 1, 90 m on other cycles) and 150 m. Each crosspiece held 8-12 cylindrical trap tubes, with an inner diameter of 70 mm and an 8:1 aspect ratio. Each tube also contained a baffle constructed of 14 smaller tubes that had been tapered at the top to ensure that all particles settling within the inner diameter of the outer tube would sink into the trap. Tubes were deployed with 2 L of a slurry comprised of 0.1-um filtered seawater, amended with an additional 50 g L-1 NaCl, and formalin (1% final concentration). Upon recovery, the height of the interface between trap slurry and overlying water was immediately determined and the overlying water was gently removed with a peristaltic pump. Samples were then gravity filtered through a 200-um mesh Nitex filter and the contents of the filter were sorted under a dissecting microscope to remove mesozooplankton that were believed to have swam into the trap. The remainder of the >200-um particles were then re- combined with the <200-um. Individual tubes were split using a Fulsom split to allow replicate measurements of multiple different components of the sinking including organic C (Corg), N, and pigments (reported in Stukel et al. 2013). Samples for pigments were filtered through GF/F filters and extracted in 90% acetone for greater than 24 hours. Chlorophyll a and phaeopigments were then determined on a Turner Designs model 10 fluorometer (Strickland and Parsons, 1972). Samples for C and N were filtered through a GF/F filter and frozen at -80C. On land, filters were cut in half and acidified with HCl for 24 hours. They were then analyzed for C and N on the CHN analyzer at the SIO Analytical Facility. Related publications and references: Knauer, G.A., Martin, J.H., and Bruland, K.W.

attribute	NC_GLOBAL	instruments_0_description	String	Floating sediment traps are specially designed sampling devices deployed to float in the water column (as opposed to being secured to a mooring at a fixed depth) for periods of time to collect particles from the water column that are falling toward the sea floor. In general a sediment trap has a container at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. The 'Sediment Trap -Floating' designation is used for a floating type of sediment trap about which no other design details are known.

attribute	NC_GLOBAL	projects_0_description	String	Research was aimed at improved understanding of plankton dynamics, carbon and nutrient fluxes, and potential trace element limitation in the Costa Rica Dome region of the eastern tropical Pacific. The specific science objectives of the 2010 R/V Melville cruise (MV1008) were: 1) to assess grazing and trace metal/nutrient controls on primary production and phytoplankton standing stocks; 2) to quantify carbon and elemental fluxes and export rates from the euphotic zone; and 3) to measure microbial population, processes, stable isotope abundances associated with the OMZ and nitrite maxima. Additional information about MV1008 can be found in the cruise report (PDF). NOTE: The original proposal and award abstract are not relevant. The project was originally funded by NSF as experimental tests of phytoplankton controls in the Arabian Sea. Piracy concerns in the region led to the cancellation of the research cruise in 2009, and a Change of Scope request was approved to focus the project on related issues in the Costa Rica Dome (CRD). Though this project is not formally affiliated with any large program, it aligns with IMBER's emphasis on community ecology and biogeochemistry, and the OCB focus on carbon-based measurements of production, grazing and export processes.
